Question

The weight of a dozen sheets of thin cardboard is 40g. How many sheets of the same cardboard would weight 5/4 kg?​

Answer 1

Answer:

375 sheets

Step-by-step explanation:

Dozen sheets of thin cardboard = 12 sheets

Weight of 12 sheets = 40g

Weight of each sheet = $\frac{40}{12} = 3.33 gm$

$\frac{5}{4} kg = \frac{5}{4} *1000 gm \\=1250 gm$

Let the number of sheets used be = $x$

$x * 3.33 = 1250 gm\\\\x = 375.375$
